Part Number: UC2843A-Q1 Other Parts Discussed in Thread: UC3843 , UC2843 Tool/software: Hello Application team:
I saw the solutions have E2E discussion including Flyback topology simulation design. But I cannot find on Webench now. May I know is there…
Part Number: UC2843A-Q1 Tool/software: Hi expert,
Do we have next generation or latest devices which can replace UC2843A-Q1 (including non-Automotive devices, customer can accept.)? Thanks.
Best Regards,
Ryker
Part Number: UC2843A-Q1 Tool/software: Hi team,
I would like to know below oscillation frequency and maximum duty cycle plot over temperature.
Is there such a data available?
regards,
Part Number: UC2843A-Q1 Tool/software:
Did TI make a design change between July 2022 and October 2024 that resulted in the changes to maximum lead temperature and package thermal impedance as cited in the October 2024 datasheet?
Was a PCN issued for…
Part Number: UC2843A-Q1 Tool/software: Hi team,
I would like to use UC2843A-Q1 a <50% duty cycle limit.
Could you advise if i can use Rt=1kohm, Ct=12nF?
I found below recommendation in the datasheet which seems to restrict the range of Rt to …
Part Number: UC2843A-Q1 Tool/software: Hi team,
UCC2843A-Q1 doesn't have Vc pin as datasheet page 8.
Is this Vc connected to Vcc internally?
In that case, OUTPUT High Voltage can be as high as Vcc?
I plans connect Vcc>15V, so I wonder if it is…
Part Number: UC2843A-Q1 Tool/software: Hi team,
I designed isolated flyback converter with opt coupler feedback. VIn=500V, Vout=8V, Po=16W at Fsw=100kHz.
When I reduce the load current to near 0A, then the switching frequency drops to 10kHz.
Is…
Part Number: UC2843A-Q1 Am planning to use this Driver IC for our design,
I need some clarification on this. When I'm doing WEBENCH with the UC2843A-Q1, there is an ISENSE pin in that circuit. I understand that it is used for sensing the current from…

Hi,
This is an urgent request. My customer is requesting simulation model for UC2843A-Q1 . Do we have simulation model in SIMPLIS or PSpice…
Part Number: UC2843A-Q1 Other Parts Discussed in Thread: UC2843 Hi, anybody have the any reference Tina Model / ref schematic for UC2843 which can take DC input of 75-150V and convert it to 14V, 10A.
